SFR surface density of Malin 1 as a function of galactocentric radius. The blue circles and brown hexagons show the central regions and the extended disk regions, respectively, obtained from the pPXF fit discussed in Sect. 2.2. The red diamonds are the Hα radial average measured in concentric rings with a width of 5″ from the center. The orange stars show the radial averages measured in the same field in the UVIT FUV image of Malin 1 from Saha et al. (2021), as shown in Fig. 6. For illustration purposes, the UV data points are horizontally shifted by 2 kpc. The green squares show the data points from Junais et al. (2020), based on the IMACS-Magellan Hα long-slit spectra of Malin 1.
